The source has been recognized as 'suse', not as 'sles':
--> <distribution name="suse" version=""/>
Are you sure it is SuSE Enterprise and not Open SuSE? Converter supports SLES only.
Anyway, you can try a hack to make it believe it is SLES - edit the "/etc/SuSE-release" on the source machine (or something similar within the pattern /etc/*-release) and in the first line add "Enterprise". Then try again the conversion. This is for the "lsuseinux90" machine.
As for "opscenter" - the version has not been recognized too. The second line in the release file should be something like "VERSION = xx".
